Another noob question..sorry T.T

Ok...so it's like this....Us hollow fight....i mean A LOT...and we get stronger....Is it possible for us hollow to do what we've been known for all our um...'dead' lives.....Eating souls....so an example...say we are fighting someone and they are dead either way.......Can't we bite their 'head off' so to speak and consume them? i mean npc are probably ok to eat but my first Question is can we..seccond is can we eat non-npc souls?

[sarcasm]No noob, you need to cremate the dead bodies and leave them there.[/sarcasm]

I would say it would be fair as Hollows are generally considered "Stronger" than Shinigami because of their growth rate, Shinigami can't absorb souls for more power so theirs isn't as high as a Hollow.Of course this comes down to Exodus.
